I can’t speak to the Trek 7300 since I’ve never ridden one. I went from a Specialized Hard Rock to my Trek Fx3 and easily gained 2-3 mph. Both would be considered hybrids ( I think), but the feel of the Trek is distinctively different and way quicker. My recommendation would be to go test ride the Fx. I noticed the quickness already in the parking lot as I tested the Fx compared to my other bike. The Specialized works better on trails than the Trek, so a different bike depending on my plans. If you don’t seem to notice any difference, don’t buy it. If you are just looking for speed, a road bike is built for more speed and you would surely notice an increase in speed if you spent $1000-$1500 on a new road bike.
